The most powerful whole-home backup solution.

EcoFlow DELTA Pro Ultra is a residential power backup system designed for both extended outages and daily use. With an unrivaled capacity of 6kWh, 7200W output, and 5.6kW solar input, a single unit can run your entire home. With the EcoFlow Smart Home Panel 2, get an uninterrupted power backup experience with automatic switch-over, energy consumption monitoring, and lower electricity bills.

One unit covers every appliance.

With a 7.2kW output, the EcoFlow DELTA Pro Ultra effortlessly runs even energy-hungry household items, like a 3-ton central air conditioner*. For more power, pair 3 inverters with the EcoFlow Smart Home Panel 2 to unlock a 21.6kW AC output. Plus, with X-Fusion, you'll get a constant 7200W output no matter what.*

One hour of solar for one day of power.

By leveraging High and Low-PV technologies, a single inverter sets new portable solar input standards with a 5.6kW input*. Connect three inverters for a monumental 16.8kW, gaining a full day's home energy in 60 minutes. Whether you prefer a portable setup or a rooftop solar system, you can achieve true energy independence.

You won't even notice the grid was down.

Imagine a world where power outages go unnoticed. With EcoFlow DELTA Pro Ultra's online UPS, you'll get just that. With uninterrupted power flow, EcoFlow DELTA Pro Ultra safeguards your vulnerable electronic equipment round-the-clock. For extended outages, you don't want to hear your backup in the background, so for low draws under 2000W*, it's completely silent. With a whisper-quiet 0 dB, your nights remain undisturbed as it powers your devices. For a maximum of 30 minutes.

Peace of mind with an advanced design.

With its flexible plug-and-play design and unrivaled solar input, the EcoFlow DELTA Pro Ultra empowers you to tailor your solution to fit your energy needs. The EcoFlow DELTA Pro Ultra includes a PV locking feature, assuring safety and a solid energy connection.

Month-long power security.

Take home power dependability to another level with up to 90kWh battery capacity. For a standard household, that's over 30 days of essential backup power to keep appliances like lights and refrigerators running strong (time may vary). Stackable and space-saving, it packs comfortably into a garage or utility closet.

Q9: What is the EcoFlow DELTA Pro Ultra Inverter's surge rating, and how long does it last?
LRA 120A; 10.8kW peak watts for 10 seconds.

Q10: Can an electrical appliance plug directly into EcoFlow DELTA Pro Ultra?
Yes. EcoFlow DELTA Pro Ultra (Inverter + Battery) works as a standalone unit powering electrical appliances of up to 7200W. There are 11 outlets on the inverter, including NEMA 5-20, TT30, L14-30 supporting 30A, USB-C, and USB-A.

Q11: What is the charging power and time of a single battery?
With only one battery pack, the fastest charging input is 6200W, taking about 92 minutes to charge from 0% to 100%. When there are two battery packs, the fastest charging input is 8800W, and it takes about 1 hour and 56 minutes to charge from 0% to 100%.

Q12: Can EcoFlow DELTA Pro Ultra power a several-ton air conditioner?
One EcoFlow DELTA Pro Ultra can power a 3 ton central air conditioning unit. 2 x DELTA Pro Ultra can power two 4-ton central air conditioning units, 3 x DELTA Pro Ultra can power three 4-ton central air conditioning units, but the LRA rating must be within 120A.

Q13: Can X-Fusion charge EcoFlow DELTA Pro Ultra from an AC outlet while it's also plugged into the Smart Home Panel 2?
X-Fusion technology ensures that all AC output sockets provide optimal output in terms of wattage and amp. In fast charging mode, the output will always be 7.2kW, no matter how much the input is. When EcoFlow DELTA Pro Ultra is connected to Smart Home Panel 2, AC charging is disabled. 5 + 8 ports and C20 charging port mutual exclusion.

Q14: Can EcoFlow DELTA Pro Ultra charge from a 15A AC outlet while delivering 240V?
When charging EcoFlow DELTA Pro Ultra with 120V, it can output 240V normally. When charging EcoFlow DELTA Pro Ultra with 240V, it cannot output 240V. When charging at 240V using X-Stream charging via an AC inlet, AC output is not available. That is to say, when charging with high voltage 240V input voltage, all AC output is disabled.
